Problems solved by technology

However, in some cases, the viscosity of the liquid ink can cause a portion of the ink to remain on the drum after the image is transferred to the media sheet, which can then degrade other images formed on the drum

Embodiment Construction

[0019] As used herein, the term "printer" or "imaging device" generally refers to a device used to apply an image to printed media and may include any device, such as a digital copier, book maker, facsimile machine, multifunction machine, etc., that Perform printout functions for any purpose. "Print media" may be thin paper, plastic solid pages, or other suitable solid print media substrates. A "print job" or "document" is generally a group of related pages, usually one or more revised copies copied from a set of original print job pages or electronic document page images, from a particular user or other related people. The term "consumable" as used herein refers to anything used or consumed by the imaging device during operation, such as print media, marking materials, cleaning fluids, and the like. Images generally contain information in electronic form, which may be provided by the image forming device on a print medium, and may include text, graphics, pictures, and the l...

Abstract

A drum maintenance system for use in an imaging device includes a reservoir having a supply of release agent. An applicator is configured to receive release agent from the reservoir and to apply the release agent to an imaging surface of an imaging device. A metering blade is positioned to meter the release agent on the imaging surface applied by the applicator. The metering blade is arranged in doctor mode with respect to the imaging surface and includes a tip positioned adjacent the imaging surface. The tip has a square portion positioned proximate the imaging surface and a beveled portion opposite the imaging surface.

Description

technical field [0001] The present disclosure relates generally to imaging devices having intermediate imaging surfaces, and more particularly to maintenance systems for such intermediate imaging surfaces. Background technique [0002] In a solid ink imaging system with an intermediate member, ink is loaded into the system in solid form (in the form of pellets or ink sticks) and transported by an input mechanism through an input chute for delivery to the heater assembly. A heated plate in the heater assembly melts solid ink that hits the plate into a liquid that is transported to the printhead for jetting on an intermediate transfer member, which may be in the form of a rotating drum, for example. In the printhead, the liquid ink is typically maintained at a temperature that enables ejection of the ink by printing elements in the printhead, but keeps the ink sufficiently viscous to bond to the intermediate transfer drum. In some cases, however, the viscosity of the liquid i...
